The Future of Capsule Endoscopy: The Role of Artificial Intelligence and Other Technical Advancements: Young Joo Yang; Clin Endosc 2020;53(4):387-394. Published online July 16, 2020; DOI: https://doi.org/10.5946/ce.2020.133

Abstract PDF PubReader ePub

Capsule endoscopy has revolutionized the management of small-bowel diseases owing to its convenience and noninvasiveness. Capsule endoscopy is a common method for the evaluation of obscure gastrointestinal bleeding, Crohn’s disease, small-bowel tumors, and polyposis syndrome. However, the laborious reading process, oversight of small-bowel lesions, and lack of locomotion are major obstacles to expanding its application. Along with recent advances in artificial intelligence, several studies have reported the promising performance of convolutional neural network systems for the diagnosis of various small-bowel lesions including erosion/ulcers, angioectasias, polyps, and bleeding lesions, which have reduced the time needed for capsule endoscopy interpretation. Furthermore, colon capsule endoscopy and capsule endoscopy locomotion driven by magnetic force have been investigated for clinical application, and various capsule endoscopy prototypes for active locomotion, biopsy, or therapeutic approaches have been introduced. In this review, we will discuss the recent advancements in artificial intelligence in the field of capsule endoscopy, as well as studies on other technological improvements in capsule endoscopy.

Abstract PDF Supplementary Material PubReader ePub

Capsule endoscopy (CE) is the first-line diagnostic modality for detecting small bowel lesions. CE is non-invasive and does not require sedation, but its movements cannot be controlled, it requires a long time for interpretation, and it has lower image quality compared to wired endoscopy. With the rapid advancement of technology, several methods to solve these problems have been developed. This article describes the ongoing developments regarding external CE locomotion using magnetic force, artificial intelligence-based interpretation, and image-enhancing technologies with the CE system.

Abstract PDF PubReader ePub

The small bowel had long been considered a dark unapproachable tunnel until the invention of capsule endoscopy and doubleballoon enteroscopy in the 21st century, which revolutionized the diagnosis and management of small bowel diseases, including bleeding. Various imaging modalities such as computed tomographic enterography, angiography, capsule endoscopy, and balloonassisted enteroscopy play vital roles in the diagnosis and management of small bowel bleeding. The choice of modality to use and timing of application differ according to the availability of the modalities, patient’s history, and physician’s experience. Small bowel bleeding is managed using different strategies as exemplified by medical treatment, interventional radiology, endoscopic therapy, or surgical intervention. Balloon-assisted enteroscopy enables endoscopic interventions to control small bowel bleeding, including electrocautery, argon plasma coagulation, clip application, and tattooing as a prelude to surgery. In this article, we clarify the recent approaches to the optimal diagnosis and management of patients with small bowel bleeding.

Roles of Capsule Endoscopy and Device-Assisted Enteroscopy in the Diagnosis and Treatment of Small-Bowel Tumors: Eun Ran Kim; Clin Endosc 2020;53(4):410-416. Published online July 30, 2020; DOI: https://doi.org/10.5946/ce.2020.161

Abstract PDF PubReader ePub

With the development of capsule endoscopy (CE) and device-assisted enteroscopy (DAE), the incidence of small-bowel tumors has increased and the characteristics of these tumors have changed. In addition, the diagnostic and therapeutic approaches for small-bowel tumors have diversified. CE is a simple, noninvasive method that aid in the visualization the entire small bowel. CE is considered the initial approach for small-bowel tumors. DAE can be used to perform endoscopic procedures such as bleeding control, polypectomy, stent insertion, and tattooing, as well as for diagnosis through visualization or tissue sampling. Therapeutic intervention with DAE is particularly useful in polyposis syndromes such as familial adenomatous polyposis and Peutz-Jeghers syndrome. This review will discuss the roles of CE and DAE in the diagnosis and treatment of small-bowel tumors.

Endoscopic Ultrasound-Guided Fine Needle Aspiration and Endoscopic Retrograde Cholangiopancreatography-Based Tissue Sampling in Suspected Malignant Biliary Strictures: A Meta-Analysis of Same-Session Procedures: Diogo Turiani Hourneax de Moura, Marvin Ryou, Eduardo Guimarães Hourneaux de Moura, Igor Braga Ribeiro, Wanderlei Marques Bernardo, Christopher C. Thompson; Clin Endosc 2020;53(4):417-428. Published online November 5, 2019; DOI: https://doi.org/10.5946/ce.2019.053

Abstract PDF PubReader ePub

Background
/Aims: The diagnosis of biliary strictures can be challenging. There are no systematic reviews studying same-session endoscopic retrograde cholangiopancreatography (ERCP)-based tissue sampling and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for the diagnosis of biliary strictures.
Methods
A systematic review was conducted on studies analyzing same-session EUS and ERCP for tissue diagnosis of suspected malignant biliary strictures. The primary outcome was the accuracy of each method individually compared to the two methods combined. The secondary outcome was the accuracy of each method in pancreatic and biliary etiologies. In the meta-analysis, we used Forest plots, summary receiver operating characteristic curves, and estimates of the area under the curve for intention-to-treat analysis.
Results
Of the 12,132 articles identified, six were included, resulting in a total of 497 patients analyzed. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and accuracy of the association between the two methods were: 86%, 98%, 12.50, 0.17, and 96.5%, respectively. For the individual analysis, the sensitivity, specificity and accuracy of EUS-FNA were 76%, 100%, and 94.5%, respectively; for ERCP-based tissue sampling, the sensitivity, specificity, and accuracy were 58%, 98%, and 78.1%, respectively. For pancreatic lesions, EUS-FNA was superior to ERCP-based tissue sampling. However, for biliary lesions, both methods had similar sensitivities.
Conclusions
Same-session EUS-FNA and ERCP-based tissue sampling is superior to either method alone in the diagnosis of suspected malignant biliary strictures. Considering these results, combination sampling should be performed when possible.

Endoscopic Ultrasound-Guided Pancreatic Transmural Stenting and Transmural Intervention: Takeshi Ogura, Hideko Ohama, Kazuhide Higuchi; Clin Endosc 2020;53(4):429-435. Published online November 27, 2019; DOI: https://doi.org/10.5946/ce.2019.130

Abstract PDF PubReader ePub

Endoscopic ultrasound (EUS)-guided pancreatic access is an emergent method that can be divided into the two main techniques of EUS-guided rendezvous and pancreatic transmural stenting (PTS). While many reports have described EUS-guided procedures, the indications, technical tips, clinical effects, and safety of EUS-guided pancreatic duct drainage (EUS-PD) remain controversial. This review describes the current status of and problems associated with EUS-PD, particularly PTS. We reviewed clinical data derived from a total of 334 patients. Rates of technical and clinical success ranged from 63% to 100% and 76% to 100%, respectively. In contrast, the rate of procedure-related adverse events was high at 26.7% (89/334). The most frequent adverse events comprised abdominal pain (n=38), acute pancreatitis (n=15), bleeding (n=9), and issues associated with pancreatic juice leakage such as perigastric fluid, pancreatic fluid collection, or pancreatic juice leaks (n=8). In conclusion, indications for EUS-PTS are limited, as is the evidence of its viability, due to the scarcity of expert operators. Despite improvements made to various devices, EUS-PTS remains technically challenging. Therefore, a long-term, large-scale, multicenter study is required to establish this technique as a viable alternative drainage method.

Published online April 7, 2020; DOI: https://doi.org/10.5946/ce.2019.118

Abstract PDF PubReader ePub

Background
/Aims: This study aimed to study the endoscopic yield, appropriateness, and complications of pediatric endoscopy performed by adult gastroenterologists in an adult endoscopic suite.
Methods
This a retrospective study in which records of all the patients less than 18 years of age who underwent endoscopy in the last 5 years were studied. The indications of endoscopy in children were categorized as appropriate or inappropriate per the latest guidelines by American Society for Gastrointestinal Endoscopy and North American Society for Pediatric Gastroenterology, Hepatology and Nutrition. Positive endoscopic yield was defined as the presence of any abnormality on endoscopy.
Results
Among the total of 822 children (age <18 years), the most common indications were variceal surveillance/eradication in 157 (19.1%), followed by dyspepsia in 143 (17.4%), upper gastrointestinal (UGI) bleeding in 136 (16.5%), recurrent abdominal pain in 94 (11.4%), unexplained anemia in 74 (9%), recurrent vomiting in 50 (6.08%), chronic refractory gastroesophageal reflux disease in 34 (4.1%) and others; 780 out of 822 endoscopic procedures (94.9%) done in children were appropriate as per the guidelines. The endoscopic yield was 45.8%, highest in patients with UGI bleeding (71.3%), followed by variceal surveillance (54.8%), recurrent vomiting (38%), dyspepsia (37.8%), and recurrent abdominal pain (36%). Minor adverse events occurred in 7.3% of children.
Conclusions
Pediatric endoscopy performed by an experienced adult gastroenterologist may be acceptable if done in cooperation with a pediatrician.

Determining the Safety and Effectiveness of Electrocautery Enhanced Scissors for Peroral Endoscopic Myotomy (with Video): Kelly E. Hathorn, Walter W. Chan, Hiroyuki Aihara, Christopher C. Thompson; Clin Endosc 2020;53(4):443-451. Published online May 22, 2020; DOI: https://doi.org/10.5946/ce.2019.214

Abstract PDF Supplementary Material PubReader ePub

Background
/Aims: Peroral endoscopic myotomy (POEM) has recently come to the forefront in the management of achalasia. We aimed to analyze the efficacy and safety of the use of electrocautery enhanced scissors (EES) for POEM.
Methods
This retrospective cohort study prospectively collected the data of all adult patients (aged ≥18 years) with normal foregut anatomy who underwent POEM using EES. The patients’ baseline characteristics and procedure details (time, tunnel length, myotomy length, depth, and location) were recorded. The primary outcome was clinical success (3-month post-procedure Eckardt score of ≤3). The secondary outcomes were technical success and adverse events. A paired Student’s t-test was performed.
Results
Fifteen patients were included in this study. The technical success rate of myotomy using EES was 100%. Fellows participated in the myotomy in all cases. The clinical success rate was 93.3% (14/15). The mean pre-Eckardt score was 5.4±2.5, while the mean post-Eckardt score was 1.3±1.3, which indicated a significant improvement (p≤0.0001). The most common treatment-related adverse events were post-procedure pain (4, 26.7%) and symptomatic reflux disease (4, 26.7%).
Conclusions
In the largest series to date on the use of EES in POEM, we demonstrated that this technique has both technical and clinical efficacy as well as an excellent safety profile.

Bleeding after Endoscopic Resection in Patients with End-Stage Renal Disease on Dialysis: A Multicenter Propensity Score-Matched Analysis: In Kyung Yoo, Chan Gyoo Kim, Young Ju Suh, Younkyung Oh, Gwang Ho Baik, Sun Moon Kim, Young Dae Kim, Chul-Hyun Lim, Jung Won Jeon, Su Jin Hong, Byoung Wook Bang, Joon Sung Kim, Jun-Won Chung; Clin Endosc 2020;53(4):452-457. Published online October 25, 2019; DOI: https://doi.org/10.5946/ce.2019.107

Abstract PDF PubReader ePub

Background
/Aims: Frequent bleeding after endoscopic resection (ER) has been reported in patients with end-stage renal disease (ESRD). We aimed to evaluate the association and clinical significance of bleeding with ER in ESRD patients on dialysis.
Methods
Between February 2008 and December 2018, 7,571 patients, including 47 ESRD patients on dialysis who underwent ER for gastric neoplasia, were enrolled. A total of 47 ESRDpatients on dialysis were propensity score-matched 1:10 to 470 non-ESRD patients, to adjust for between-group differences in variables such as age, sex, comorbidities, anticoagulation use, tumor characteristics, and ER method. Matching was performed using an optimal matching algorithm. For the matched data, clustered comparisons were performed using the generalized estimating equation method. Medical records were retrospectively reviewed. Frequency and outcomes of post-ER bleeding were evaluated.
Results
Bleeding was more frequent in the ESRD with dialysis group than in the non-ESRD group. ESRD with dialysis conferred a significant risk of post-ER bleeding (odds ratio, 6.1; 95% confidence interval, 2.7–13.6; p<0.0001). All post-ER bleeding events were controlled using endoscopic hemostasis except in 1 non-ESRD case that needed surgery.
Conclusions
ESRD with dialysis confers a bleeding risk after ER. However, all bleeding events could be managed endoscopically without sequelae. Concern about bleeding should not stop endoscopists from performing ER in ESRD patients on dialysis.

Efficacy and Safety of Endoscopic Treatment for Gastrointestinal Stromal Tumors in the Upper Gastrointestinal Tract: Cicilia Marcella, Shakeel Sarwar, Hui Ye, Rui Hua Shi; Clin Endosc 2020;53(4):458-465. Published online March 17, 2020; DOI: https://doi.org/10.5946/ce.2019.121

Abstract PDF PubReader ePub

Background
/Aims: Endoscopic treatment (ET) has been applied for decades to treat subepithelial tumors, including gastrointestinal stromal tumors (GISTs). However, the efficacy of ET remains debatable. In this study, we evaluated the efficacy and safety of ET for GISTs in the upper gastrointestinal tract.
Methods
This retrospective single-center study included 97 patients who underwent ET. All patients were enrolled from July 2014 to July 2018. Parameters such as demographics, size, resection margin, complications, pathological features, procedure time, total cost, and follow-up were investigated and analyzed.
Results
Our study achieved 100% en bloc resection and 77.4% (72/93) R0 resection. The most common location was the fundus with a mean tumor size of 2.1±1.43 cm. The mean age, procedure time, hospital stay, and cost were 59.7±11.29 years, 64.7±35.23 minutes, 6.8 days, and 5,337 dollars, respectively. According to National Institutes of Health classification, 63 (64.9%), 26 (26.8%), 5 (5.2%), and 3 (3.1%) patients belonged to the very low, low, intermediate, and high risk classification, respectively. Immunohistochemistry results showed a 100% positive rate of CD34, DOG-1, CD117, and Ki67. A mean follow-up of 21.3±13.0 months showed no recurrence or metastasis.
Conclusions
ET is effective and safe for curative removal of GISTs in the upper gastrointestinal tract, and it can be a treatment of choice for patients with no metastasis.

Endoscopic Findings in Patients Under the Age of 40 Years with Hematochezia in Singapore: Man Hon Tang, Fung Joon Foo, Chee Yung Ng; Clin Endosc 2020;53(4):466-470. Published online June 18, 2020; DOI: https://doi.org/10.5946/ce.2019.029

Abstract PDF PubReader ePub

Background
/Aims: Sigmoidoscopy is performed in most medical centers to evaluate the distal colons of young adults presenting with hematochezia who are at risk of developing proximal lesions. Colonoscopies offer more complete evaluations but are associated with a higher incidence of complications and possible low yield.
Methods
An analysis was conducted on colonoscopies performed in our center on patients 40 years of age or younger. The study population was sub-divided into 2 age groups for analysis: <30 years of age and 30–39 years of age.
Results
We recruited 453 patients for the study. Patients were 115 and 338 individuals that were <30 and 30–39 years of age, respectively. Hemorrhoids was identified as the cause of bleeding in the majority of cases. The overall incidence of polyps was 6.5%; this was significantly higher in the 30–39 age group (7.4% vs. 1.7%, p=0.026). There were two cases of advanced/malignant polyps. While the majority of the polyps were in the distal colon, 28% of the polyps in the older age group were found in the proximal colon. There was one case of colonic perforation.
Conclusions
Colonic polyps are more prevalent in patients aged 30–39. Colonoscopies should be considered for patients over the age of 30 with rectal bleeding.

Modified Endoscopic Ultrasound Needle to Obtain Histological Core Tissue Samples: A Retrospective Analysis: Munish Ashat, Kaartik Soota, Jagpal S. Klair, Sarika Gupta, Chris Jensen, Arvind R. Murali, Randhir Jesudoss, Rami El-Abiad, Henning Gerke; Clin Endosc 2020;53(4):471-479. Published online February 5, 2020; DOI: https://doi.org/10.5946/ce.2019.108

Abstract PDF PubReader ePub

Background
/Aims: Endoscopic ultrasound (EUS)-guided fine-needle aspiration is very effective for providing specimens for cytological evaluation. However, the ability to provide sufficient tissue for histological evaluation has been challenging due to the technical limitations of dedicated core biopsy needles. Recently, a modified EUS needle has been introduced to obtain tissue core samples for histological analysis. We aimed to determine (1) its ability to obtain specimens for histological assessment and (2) the diagnostic accuracy of EUS-guided fine-needle biopsy (EUS-FNB) using this needle.
Methods
We retrospectively analyzed consecutive cases of FNB using modified EUS needles for 342 lesions in 303 patients. The cytology and histological specimens were analyzed. Diagnostic accuracy was calculated.
Results
Adequate cytological and histological assessment was possible in 293/342 (86%) and 264/342 (77%) lesions, respectively. Diagnostic accuracy of the cytological specimen was 294/342 (86%) versus 254/342 (74%) for the histological specimen (p<0.01). Diagnostic accuracy of the combined cytological and histological assessment was 323/342 (94.4%), which was significantly higher than that of both histology alone (p<0.001) and cytology alone (p=0.001).
Conclusions
EUS-FNB with the modified EUS needle provided histologic tissue cores in the majority of cases and achieved excellent diagnostic accuracy with few needle passes.

Efficacy and Safety of Lumen-Apposing Stents for Management of Pancreatic Fluid Collections in a Community Hospital Setting: Rajat Garg, Abdelkader Chaar, Susan Szpunar, Babu P. Mohan, Mohammed Barawi; Clin Endosc 2020;53(4):480-486. Published online October 16, 2019; DOI: https://doi.org/10.5946/ce.2019.116

Abstract PDF PubReader ePub

Background
/Aims: Endoscopic ultrasound-guided transmural drainage and necrosectomy employing lumen-apposing metal stent (LAMS) are used for treating pancreatic fluid collections (PFCs) with excellent results from academic centers. Herein, we report the efficacy and safety of LAMS in the treatment of PFCs at a community hospital.
Methods
We retrospectively reviewed the etiology of pancreatitis, type and size of PFCs, length of procedure, technical success, clinical success, adverse events, and stent removal. The primary outcome was the rate of clinical success, and secondary outcomes were technical success and adverse events.
Results
Twenty-seven patients with a mean age of 54.1±6.5 years were included, 44% of which were men. The mean size of the PFCs was 9.7±5.0 cm (range, 3–21). The most common etiology of pancreatitis was alcohol (44%) followed by idiopathic causes (30%) and presence of gallstones (22%). The diagnosis was pseudocyst in 44.4% (12/27) and walled off necrosis in 55.6% (15/27) of patients. There was 100% technical success without any complications. Clinical success was achieved in 22 of 27 patients (81.5%) who underwent stent removal.
Conclusions
Our study is the first to report that endoscopic therapy of PFCs using LAMS is safe and effective even in a community hospital setting with limited resources and support compared to large academic centers.

Endoscopic Submucosal Dissection of a Colonic Calcifying Fibrous Tumor: Jaeyoung Kim, Seongyul Ryu, Yeon-Ji Kim; Clin Endosc 2020;53(4):487-490. Published online January 21, 2020; DOI: https://doi.org/10.5946/ce.2019.138

Abstract PDF PubReader ePub

A 49-year-old woman was referred to our hospital for further treatment due to the suspicion of a submucosal tumor in a routine screening colonoscopy. On colonoscopy, a 1-cm sized subepithelial mass with normal overlying mucosa in the hepatic flexure was found. Endoscopic ultrasonography (EUS) showed a homogenous hypoechoic lesion arising from the second and third layer. We were unable to make a final diagnosis because the lesion showed a small tumor with atypical macroscopic morphology including EUS findings. Therefore, endoscopic submucosal dissection was performed for the diagnostic treatment of the tumor. Submucosal dissection was performed just above the muscle layer, and the tumor was removed completely and reliably without any acute complications such as perforation. Based on histopathological findings, we diagnosed a benign, calcifying fibrous tumor (CFT). The present case is the first report of successful endoscopic diagnosis and treatment of colonic CFT mimicking a submucosal tumor.

Abstract PDF PubReader ePub

In this study, we assessed a series of our cases in which endoscopic self-expandable metal stents (SEMSs) were used to treat malignant afferent loop obstruction (ALO) that arose after pancreaticoduodenectomy (PD). We retrospectively examined the records of 7 patients who underwent endoscopic SEMS placement for malignant ALO following PD. Clinical success was achieved in all cases. The median procedure time was 30 min (range, 15–50 min). There were no cases of stent occlusion, and no procedure-related adverse events were encountered. All patients died of their primary disease, and the median overall survival period was 155 days (range, 96–374 days). A re-intervention involving endoscopic ultrasound-guided hepaticogastrostomy combined with antegrade stenting was performed for obstructive jaundice and acute cholangitis in 1 case. In conclusion, endoscopic SEMS placement may be an effective and safe treatment for malignant ALO that arises after PD.
